           DESCRIPTION "This object contains an OBJECT IDENTIFIER
                       which identifies the chipset used to
                       realize the interface. Ethernet-like
                       interfaces are typically built out of
                       several different chips. The MIB implementor
                       is presented with a decision of which chip
                       to identify via this object. The implementor
                       should identify the chip which is usually
                       called the Medium Access Control chip.
                       If no such chip is easily identifiable,
                       the implementor should identify the chip
                       which actually gathers the transmit
                       and receive statistics and error
                       indications. This would allow a
                       manager station to correlate the
                       statistics and the chip generating
                       them, giving it the ability to take
                       into account any known anomalies
                       in the chip."

                       useful in determining the approximate distance
                       to a cable fault.  It is advisable to repeat
                       this test to check for a consistent resulting
                       TDR value, to verify that there is a fault.

                       A TDR test returns as its result the time
                       interval, measured in 10 MHz ticks or 100 nsec
